Top Screw Metal Corporation was founded in 1975 and during the leaping phase of industrialization in Taiwan. Top Screw started by manufacturing semi-tubular rivets and screws for hand bags and luggage industries. Top Screw specializes in manufacturing threaded binding posts, bolts, and rivets for bicycling, electronics, cutleries, and furniture products. This set up a strong foundation of Top Screw for future growth and expansion. We are also well-known for specializing in Tubular Rivets, internally threaded bolts and post with excellent quality and on-time delivery by “Cold Heading” machines in Taiwan. Our business has increased steadily.

For more than 30 years, Top Screw has always believed and practiced “PRACTICALITY, RESPONSIVENESS, and UNLIMITED IMPROVEMENT” offering quality and cost effective fasteners supporting customers in global market. Top Screw has always been a pioneer in the development of fasteners, such as blind rivets, blind rivet nuts, customized fasteners, in Taiwan and we are certified with ISO-9001; ISO-9001:2000 and was accredited to ISO 14001:2004 since 1998 to 2008.

 

INVENTIONS AND PATENTED PRODUCTS:

 

Top Screw has designed several ingenious products for the purpose of streamlining production and fast in delivery, they were also rewarded for more than 10 patents in Taiwan, and two of the inventions were also rewarded in Europe and USA, which are:

 

1982 - Top Screw represented Taiwan competing in IENA81 (Internationale Ausstellung “Ideen-erfindungen-neuheiten” Nurnberg 1981) Expo. In Germany with Capped self-piercing rivet, and was rewarded with a Silver Medal.

We have expanded from the Nan Yau factory to the new Tay-ho Facility, which was twice larger than the previous capacity. Since 1989, we started to export our products to Europe, America, the Middle East, Southeast and Northwest Asia. Our monthly productions exceeded 50 million pieces after high-tech multi-stroke cold heading machines were adapted in 1990.

 

In order to stay competitiveness, we have adapted the following testing machines: -

  • ·         Computerized Torque and Tensile testing machine;
  • ·         Tensile testing machine;
  • ·         Micro Vicker Hardness Tester;
  • ·         3D Profile Projector;
  • ·         Image Display Sorting Machine

 

Our Production Equipment

  • ·         Cold Forging Production Line
    • Top Screw knows "accuracy & speed" are the most important and necessary conditions for a production line. So our Forging Department uses the most precise and advanced High-Tech Multi-Process Cold Heater equipment, from 1-dies-2-blow to 6-dies-6-blow, so we can produce various fasteners from Ø3mm. Our production is around 12 million by 8 hours per day and 24 working days per month. We trust "high quality production lines" can supply customers more competitive products by elastic delivery.  

 

  • ·         Automatic Thread Tapping Lines
    •   Top Screw Tapping Department was founded in 2004. We have Full Automatic Thread Tapping Machines and Second Process facilities. These equipments used for all kinds of special screws, nuts, insert nuts and so on. Before production, we tap some samples first, then measure and ensure the dimensions meet the working order. During the production, we change taps and tools after a fixed quantity. When the part is finished, we examine full sizes by Image Display Sorting Machine and 100% inner thread by hand.

 

  • ·         Automated Warehouse
    •    We have average over 500 thousand pieces of each standard product in stock and confidence to supply the goods within the shortest time.

 

The Industrial development is like an exposition of technology. The technology advances with time, but parts cannot become a product without fasteners like screws, nuts, rivets…etc. It might only play a small part in the product, but it is crucial to the quality of the products, so fasteners are also called “Basic Components of Industries”.

Top Screw R&D team has deep product development abilities. We can offer a complete development program according to customers’ special needs and purposes. Based on many years’ experiences, we supply most economic, practical and satisfied products to our customers.
